Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608042, here are decompositions:

5 + 31608037 = 31608042
13 + 31608029 = 31608042
29 + 31608013 = 31608042
71 + 31607971 = 31608042
73 + 31607969 = 31608042
139 + 31607903 = 31608042
173 + 31607869 = 31608042
211 + 31607831 = 31608042

Showing the first eight; more decompositions exist.
